摘要： An apparatus for sintering a cement clinker in which preheated powdered raw materials are granulated and sintered in a single fluidized bed granulating and sintering furnace. The apparatus includes a first classifying station having a discharging grooved portion extending from the fluidized bed furnace to an opening in a radial direction and communicating with a gas distributor. The space above the discharging grooved portion diverges from the opening to a fluidized bed upstream of the gas distributor so that the total velocity of air blown through the opening and from nozzles in the discharging groove is constant. A second classifying station is in communication with the opening for blowing back small particles to the fluidized bed. In a third classifying station, a discharge chute is connected to a fluidized bed cooling unit for quenching granulated and sintered clinker while small particles are blown back to the granulating and sintering furnace.
